Pregnancy generates particular circumstances for all co-existent conditions. Associating pregnancy with liver diseases has distinct particularities. The authors will perform a presentation of the etiopathogenic, diagnosis and therapeutic conduct particularities regarding the association between pregnancy, chronic liver diseases and mental disorders. The three pathological entities are analyzed separately, followed by a study of a triple association. Associating pregnancy and mental disorders has been better studied due to a higher frequency of mental disorders, especially postpartum, but the triple association pregnancy, chronic hepatitis with viral etiology mainly, and mental disorders has been less analyzed. There is concluded that pregnancy, through the physiological changes it undergoes, as well as its pathology, represents a clearly influencing factor of the association with a chronic liver disease or with a mental disorder.
